Dark gray limestone matrix with unknown fossils, corals? bryozoans? something else?
Bullsnake replied to SPrice's topic in Fossil ID
The first item reminds me of a brachiopod valve (derbyia?). I agree with bryozoan for the other. I love that picture, also! -
I love how the basal structure is shown on the bryozoan, and also the associated brachiopod. Makes me wonder how they are taphonomically associated.- 2 comments

I went on a little road trip with my brother for non-fossil related purposes. So I didn't take my camera or gear, but lo and behold, on the way he said, "There's a road cut I want to show you if you want to take a look at it." Oh well. I'm sure I'll make a trip back to it. Turned out to be pretty productive, not to mention it's right next to a construction quarry. I took down info, so I'll make a pitch to them. Upper Pennsylvanian Virgilian Series Shawnee Group Oread fm. Size range is 2 - 2.5cm. They all seem to have grown from a central stem, not unlike a mushroom as seen by the larger one still attached to the matrix. Top view of typical specimen: Bottom view: Micro views: Top Bottom Bottom variation Other organisms found at the site include: Brachiopods- Hustedia, Composita, Chonetid, Meekella. Crinoid, Cephalopod, Horn Coral. There was also a nice Syringopora coral, but needed tools to collect it. (Or at least the camera for a picture) Thanks for the help!

I'm thinking a very nice example of fenestrate bryozoan base.
-
I can't help either, but looks similar to some I found a few years ago. http://www.thefossilforum.com/index.php?/search/&q=Bryozoan&author=Bullsnake&sortby=relevancy

Does anybody recognize this? I'm guessing a dermal denticle, but the elongated shape is unusual to me. Other microfauna in the matrix includes shark(cladodont) teeth, fish teeth, gastropods, goniatites, crinoid and echinoid plates and spines, ostracods, brachiopods, bryozoan, and conodonts. For scale field of view= ~1cm. Magnification 20X Magnification 40X

An Afternoon Hunt In The Pennsylvanian Lansing Group
Bullsnake replied to Missourian's topic in Fossil Hunting Trips
A little baby pygidium: Horn coral- Notice one with the bryozoan attached: Lacey Bryozoan- These are really common, but I thought this was a cool 'layer cake':
-
Upper Pennsylvanian, Missourian stage, I believe Lansing group. Haven't pinned down the strata. These were found on the ledge between the arrows. The ledge is maybe a 10-15 foot wide 'deck', in front of the uppermost outcrop shown in the picture. Below this, on the slope I found what I think is Myalina, and Aviculopecten, which is indicative of Rock Lake Shale member, but I really don't know what it is. I'm assuming they are crinoid parts, but can't find any pictures that look like these. Also found in the area Various brachs Horn coral Bryozoan Crinoid stems and plates (stem on the left is bryozoan encrusted) Another shot of the roadcut

Hi Sasquatch, The first pic in your first post looks like a bryozoan, or something bryozoan encrusted. I wonder if the leaf-impression-looking-thing in your second post is a dermal denticle impression.
-
These are in limestone blocks in a public park so I could not collect, nor can I identify the formation they're from. My assumption is local, Pennsylvanian period. Please correct my general id of these items. Crinoid spine Crinoid calyx Gastropod molds Ichnofossil (app. 12 in. section of about 3-4 feet) Bryozoan and Coral (or just Bryozoan) I know, I need a better camera (and skills). Thank you Steve
-
Perhaps an encrusting bryozoan, or algae. It somewhat reminds me of these bryozoa I found. Pennsylvanian, Virgilian series.
-
The lace coral may also be a type of bryozoan of the fenestrate type. Pretty common and typical in the K.C. Pennsylvanian. The 'grains' are likely foraminifera called fusulinids. I'll link some posts about these this evening...off to work now.
-
I'm kind of seeing encrusting bryozoan, or maybe even sponge. Short of that I'd say concretion. What is the size, and do you know where it came from?
-
Very nice specimen and prep. That other part (the parallel 'rays') doesn't really look bryozoan to me. Or am I not seeing it right?
-
Hi, and welcome to the forum! Nice finds! Pictures 2 and 3 look like a bryozoan, the lacey (fenestrate?) type. Probably a cast. 4 and 5 look like a spiriferid brachiopod. Maybe another cast. 6 and 7 look like a brachiopod also, of a different type. An impression. 1, 8, and 9, I haven't a clue! That's the best I can do. There are many more members here that can probably be more specific. EDIT: You beat me Tim!
-
Pinniretepora. I've been finding this in the scope. I figured bryozoan, but hadn't looked it up yet. (Stuff is kind of packed away for moving right now) World class thread, Mitch!
-
Nice! Looks like one of the corals is bryozoan encrusted, too!

First Time, Found Some Fossils In Jacksonville Texas (East Texas)
Bullsnake replied to donnye's topic in Member Collections
Not sure, but this appears to be a mollusc of some sort: And this one appears to be an imprint of a lacey type of bryozoan: I can't make anything out of the others that I'm familiar with. Hope this helps! -
Hickory Creek shale finds. Thanks to Missourian for showing us what to look for, I finally have sponge specimens (another first): Loose pieces: And 3 different perspectives in matrix ( 2 different cross section views, and a 3D piece): Crinoid cups, and a stem encrusted with Bryozoan: Various Brachiopods, Horn coral, and a tiny Trilobite pygidium (just above the 4cm mark on the ruler): And finally, another first, part of a Cladodus shark tooth: I had to spotlight it with a flashlight to get any detail out of it! I think everyone had a great time, and found some neat stuff, but... wait 'til you get a load of JeepDigger's finds. He did pretty well that day!
-
Now for texture. Pennsylvanian shark tooth: Credit to Missourian for explaining this Worn oolites (Note the complete oolites in the surrounding matrix): Bryozoan (Fistulipora?) Note the rougher texture, and appears to be same material as the matrix: I think you get the idea!
-
Thanks, Indy. A search led me to your site, as well. There is a Mississippian example, I believe on an archimedes bryozoan..
-
Nice looking piece! It looks like an encrusting bryozoan is on it, too! Can you explain (without going over my head)?
-
Again, no clue on this one either: On this, I initially thought it was a bryozoan when I found it, but I'm kind of thinking mollusc: I apologize for id questions in the wrong forum, but I thought the whole story might give better perspective. Thanks for looking! Steve

Bryozoans And Corals. Age? Genus? Formation?
Bullsnake replied to KansasFossilHunter's topic in Fossil ID
By the KGS map, it is Pennsylvanian. It looks like the city sits on the border of the Shawnee and Douglas groups. If the bryozoan you are questioning is the 1st picture on the bottom row, I think it is coral. Nice finds! -
I'm thinking maybe Evactinopora bryozoan.
